Умоляю, помогите
Буду очень благодарна!

Answer 1

1.
а)
$frac{5x}{2} times frac{6}{ {x}^{2} } = 5 times frac{3}{x} = frac{15}{x}$
б)
$(x - 1) times frac{2x + 1}{3x - 3} = (x - 1) times frac{2x + 1}{3(x - 1)} = frac{2x + 1}{3}$
в)
$frac{3x + 6}{x - 3} times frac{4x - 12}{ {x}^{2} - 4 = } = frac{3(x + 2)}{x - 3} times frac{4(x - 3)}{(x - 2) times (x + 2)} = 3 times frac{4}{x - 2} = frac{12}{x - 2}$
